"DP2358 is a high performance current mode PWM power switch for offline flyback converter applications. In DP2358, PWM switching frequency with shuffling is fixed to 65KHz and is trimmed to tight range. The IC has built-in green and burst mode control for light and zero loadings, which can achieve less than 75mWstandby power. DP2358 integrates functions and protections of Under Voltage Lockout (UVLO), VDDoverVoltage Protection (VDD OVP), Cycle-by-cycleCurrent Limiting (OCP), OverLoad Protection(OLP), On-Chip Thermal Shutdown (OTP), Soft Start, VDD Clamping and CS Pin Float Protection, etc.
